the devialet version is 10.1.0 as mentioned.
The server is a windows home server 2011 which is based on windows server 2008. The whole network is cat5e cabled to a 1gbit switch. The whole house is in fact designed and built around high bandwidth audio streaming. So the server is connected to the switch and so is the devialet.
There are various ipads and laptops connected wirelessly into the system to be used as remote controllers.
I cannot remember right now what I precisely disabled, but can check the firewall settings later to see.
